Application filed March 30, 1909. Serial No. 486,688.

To all whom it may concern:

Be it known that I, GEORGE AnnLoR Ronnn'rs, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is the specification.

My invention relates to non-refillable bottles, and the object of the invention is to provide a bottle which cannot be refilled and from which liquid can be poured readily when desired.

A secondary object is to provide the parts which are inserted in the neck of the bottle so that they can be easily placed in position, and when once in position cannot be withdrawn, and also to constructsuch parts at moderate cost and with little workmanship.

It consists essentially in a bottle having a valve seat formed in the neck thereof and a groove within the neck above the valve seat; an annular supporting plate having springs secured thereto designed to pass within the groove, a protecting cage carried by the plate, a vertical rod secured to the cage and having at its lower end a spider adapted to enter the opening continuous with the valve seat, an arched'spring on the rod and beneath the cage, and a weighted valve and a float valve on the rod, the weighted valve fitting the valve seat, the parts being an ranged and constructed as hereinafter more particularly described.

Figure 1 represents a portion of a bottle in longitudinal section with my non-refilling attachment secured in the neck thereof, the bottle being in the upright position. 1 Fig. 2 represents a longitudinal sectional view of the neck of the bottle with my invention applied, the neck being shown in the inverted position. Fig. 3 represents an enlarged de' tailed perspective view of the attachment which I provide to be placed in the neck of the bottle. Fig. .t is an enlarged detailed perspective view of one of the arms extend ing from the upper plate of the cage.

In the drawings like characters of referfigure.

1 represents the body of a bottle of which 2 is the neck, and 3 the stopper or cork.

4 represents an enlargement formed at the 1 sets of downwardly extending lips 10 and r 11, respectively, those 10 and those 11 being spaced at equal intervals around the circumference of the plate, the lips 11 being situated so that they appear in each instance but a short distance from one of the lipslO. Thelips 11 have three transverse slits 11 formed therein and the lips 10 are provided with a central opening 10.

12 are flat springs having each an end 12 bent outwardly substantially at right angles to the body portion and they are secured to the plate by inserting and passing the unturned end into and through the slits 11. The turned end of each spring passes through the opening 10 being directed from the inner side of the lip outwardly. According to this construction the ends 12 of the springs are depressible inwardly and have no lateral movement as the openings 10 receive them snugly.

13 is a cage formed from an upper circular plate 14 and a lower circular plate 15. These plates are secured to each other and to the central plate by the following construction. The plate 14-. is provided with four downwardly extending arms 16 which have the upper portion 16 thereof considerably wider than the lower portions 16 so that a shoulder is formed at 16 on each of them. a

17 are four openings in the plate 8 adapted to receive the lower or narrow portion of the arms 16. The shoulders 16 in this way abut the upper face of the plate 8. The plate 15 has four upwardly directed arms 18 similar to those 16 which have the lower portions 18 thereof considerably wider than the upper portions 18 so that a shoulder is formed similar to that 16 on the arms 16, which shoulders in each case abut the under face of the plate 8 directly to the side of the openings 19 therein, the openings being of a size to receive snugly the upper ends 18 of the arms. It will be understood that the openings 19 and 17 are spaced at equal distances in the plate 8 and are alternately arranged. The plates 14 and 15 are also each provided with four openings which are designed to receive the ends of the arms 16 and 19, respectively, the ends of the arms passing through the openings and being turned downwardly against the face of the adjoining plate. In this way the plates 14 and 15 are secured to each other and held in a definite relation to the plate 8, each being prevented from movement away from the plate by the shoulders on the arms of the opposite one, and from movement toward the plate by the shoulders on its arms. The plate 15 is provided with an upwardly turned edge 20 formed from lips, the purpose of which will later become apparent.

21 is a rod secured at its upper end to the plate 14 and passing centrally through the opening 9, the lower end being provided with a spider 22 which is adapted to fit within the opening 6 thereby preventing the rod from lateral displacement.

23 is a weighted valve having its face 23 formed to fit the valve seat. The valve is free to slide on the rod 21 which passes centrally through it.

24 is an arched fiat spring threaded on the rod and having its upper end bearing against the under face of the plate 15 and its lower end against the upper face of the valve 23. The spring has a slight play allowed its lower end by the opening 25 being slightly elongated. It is to be understood that the opening in the opposite end of the spring through which the rod passes is of a size just sutlicient to receive the rod.

26 is a floating valve free to slide on the rod 21 between the ends of the spring.

By the construction described above it will be seen that all the operating parts of the device are secured to or carried by the plate 8 which is inserted in the neck of the bottle after the ends 12 of the springs have been pressed inwardly. As soon as the springs are opposite the groove the ends 12 spring out into the groove and in so doing lock the plate in a set position. The spider 22 is then within the opening 6.

To understand the invention I will now describe the operation of the valves in various positions of the bottle, assuming the bottle filled with liquid in the first instance. When the bottle is being inverted and comes to the horizontal position the valve 23 remains closed by virtue of the spring pressure. As it is turned completely to the inverted position the pressure of the liquid and the weight of the valve itself overcomes the pressure of the spring and the liquid flows from the bottle, provided the cork be withdrawn. The flowing of the liquid will not affect the float valve when this operation is taking place. It is impossible to tamper with the valves with a wire or such like as its passage to the valve would be prevented by the cage.

The advantage of the floating valve is now explained. Bottles of this class have been refilled by inverting them and inserting the neck in the liquid and at the same time withdrawing the air from the bottle thus forcing the liquid into the bottle by atmospheric pressure. If one try to fill my bottle in this manner they will find it impossible, as, as soon as the rising liquid reaches the floating valve it passes upwardly with it and in its upward passage carries or forces the valve 23 with it so that prior to the liquid reaching the opening 6 the valve 23 has seated. In pouring the liquid from the bottle it passes through the opening 6 to the plate 8 and through the opening 9 where it escapes to the exterior over the plate 14.
